CPS
With a total use of 74 protemp molars, the CPS evaluation team felt this product was a very good product with
some slight recommended changes. Most all felt it did save time, but some argued the price. Most consultants
found they did not need to use the size selection ruler. Trimming and adapting to the margins of the crown were
easy to do. Some of the consultants felt they needed to reline with a bisacrylic material. Most felt that there was a
slight learning curve. After about 3 crowns used, most of the evaluation team felt they had developed their own
technique. One evaluator said when in doubt, cut more of the material. When forming the occlusion, have the
patient bite slowing together several times. If the crown is still to high it will break or split. Another consultant said
that they were using them for bridges, when teeth are missing as an alternative to denture teeth. The CPS
evaluation team is eagerly awaiting the Anterior Pro-temp Crown and hopes for other shades.
